the problem is that you are being extremely narrow minded. you are looking at one possible way that it works out without giving any credit to the fact that there are other ways.
No, I'm fully aware of the the other ways to get into the playoffs. However, you must first and foremost try to secure the division. Only after that do you worry about the wild card.
In this situation, the Saints MUST win out, whether or not you're looking at wild card or division.
Because of this, they will have swept the Bucs and the Bucs would have no better than the same record (11-5) as the Saints; the first tiebreaker is head to head, so the Saints would win that. Therefore, my saying to pull for the Bucs IS IN FACT taking your "look to the wildcard" into account.
we are looking at another, one that is easier and mathematically more realistic.
The Saints have to win out in any situation, so Tampa is out of the equation.
your way is based on the Saints winning out. ours is based on the Saints losing one game.
If you go in assuming a loss, then you aren't getting into the playoffs.
My assumption is that in order for the Saints to make the playoffs, they must win out. That is the most realistic and easy assumption. One loss, and you can consider us done.
